Indoor and outdoor splashing
There are three public swimming pools in the city. Beside the closed hours for clubs and swimmingschools they all have recreational hours when one can go to swim. Aquadrome is the biggest one and has two different areas - a tropical bath and a regular water-basin. The tropical area has several attractions such as a slide, whirlpool and waves and is open every day of the week. The regular basin has a limited scedule for free swimming.
On hot summerdays you can also swim in the Rutbeek, a large recreational outdoor area. Beside a large swimming lake you can also find a waterski, surfarea, playgrounds and several fields for outdoor sports.
